The distribution of normal matter precisely determines gravitational acceleration in all common types of galaxies, a team led by Case Western Reserve University researchers reports. The team has shown ...

The James Webb Space Telescope’s first picture released to the public showed off thousands of galaxies. At first glance, the pinpoints of light shining in the blackness of space look like little stars ...

The existence of massive, elliptical galaxies in the early universe has puzzled astronomers for two decades. An international ...

In research published today, Australian scientists have taken a critical step towards understanding why different types of galaxies exist throughout the universe. The research, made possible by ...

Astronomers have spotted a pair of galaxies in the act of merging 12.8 billion years ago. The characteristics of these galaxies indicate that the merger will form a monster galaxy, one of the ...

The earliest galaxies are thought to have formed as the gravitational pull of dark matter, which has been impossible to study directly, slowly drew in enough hydrogen and helium to ignite stars. But ...

Four galaxies crowd the center of a collapsing structure 1.4 billion years after the Big Bang. Each one is churning out stars at a pace that defies comparison with the present-day universe. Around ...

In 1963, Caltech researcher Maarten Schmidt had a eureka moment. He was looking at the spectrum of a mysterious object named 3C 273, a source that had been found and cataloged with then-novel radio ...

New radio observations of molecular gas reveal how dozens of galaxies could have rapidly merged together in the early Universe.
